Yes. According to a Clemson University Cooperative Extension entomology fact sheet: Flea larvae avoid light, burrowing into carpets, cracks, or if outdoors, soil. The larvae feed on small particles of animal or plant debris and adult flea feces until they achieve full growth. Larval development may require as little as five days but may be extended for up to three weeks, depending on food and environmental conditions. It is a good idea to rake up the plant litter.
